FASTENER-INSERTING MACHINE.

Application filed May 20, 1920, Serial No. 382,872. Renewed Octoberfl,1923.

T 0 all whom it may concern:

Be it known that I, PERLEY R. GLASS, a citizen of the United States,residing at Wayland, in the county of Middlesex and State ofMassachusetts, have invented certain Improvements in Fastener-InsertingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to fastener inserting machines such as those usedfor inserting eyelets or other fasteners in shoe uppers and otherarticles. According to one as ect an object of the invention istoprovice a machine of relatively small cost without sacrificing accuracyor efliciency. By way of illustration the drawings represent a machineadapted to be operated by a treadle but it will be apparent that theseveral features hereinafter set forth may be embodied with equalutility in machines operated by factory power.

One particular object of the invention is to provide improved means forsupporting and reciprocating the raceway by which the fasteners aresupplied to the setting or inserting mechanism. It is necessary, fromtime to time, to change from fasteners of one size to those of another,and since the raceway is not generally usable for fasteners of more thanone side it is necessary to take off one raceway and substitute anotherwhenever fasteners of a different size are required. Accordingly afeature of the invention consists in an improved raceway carriage andimproved means for attaching the raceway to it so that various racewaysmay be interchanged without disturbing the carriage or its operatingmechanism. In this respect the invention consists in improved means formounting the carriage so that its connection with the machine will beseparate and distinct from the means employed for securing the racewayto the carriage.

Another object of the invention is to pro vide improved means foradjusting the racewa so that it will register with the tool by which thefasteners are taken from it. For

this purpose the raceway is mounted so as to be adjustable angularlyabout an axis in addition to being otherwise movable to presentfasteners successively to the aforesaid tool. Another feature of theinvention relating to this aspect of the invention consists inconstructing th e aforesaid adjusting means so as to maintain africtional holding efiect on the carriage timing of the movements of theraceway will be insured;

whereby the desired 60 Another object is to provide a raceway and hopperof relatively light construction and small cost in conjunction withreinforcing means whereb y each race-way and hopper, on being attachedto the machine, will be braced adequately to counteract the lightness ofconstruction.

feature of the invention conslsts 1n provlding a raceway-carriage Inthis respect a to which any one of a set of combined racewavs andhoppers may be readily attached, and which embodies a construction thataffords the desired reinforcement to the raceway hopper. This the numberof racewa ys included in a set 3 furnished for each machine. i Otherfeatures of the invention are1llustrated by the drawing described andclaimed.

Referring to the drawings, Fig. 1 represents a side elevation of a andare hereinafter fastener inserting machine the several. movable elementsof whichare shown initial positions;

-'llli 11'l6l1ilOQ-I'S and 37-ars= provided with wine portions 4-0 and"41 respectively, the portion 40 being arranged to bear and slide onanadjusting screw A2, hile the wing is arran'eedto bear andslideonasfpringpressed plunger 43. Tins-screwand the -plunger -arearranged in por't'ionspf the "frame 10 at'opposite sides of. thelongitudinal vertical plane of-the rod 35, the plunger maintainingupward pressure against the wing- 41' and thereby'm'aintainiiig downwardpressure of the wingz l0 on the screw 42. lVhenever thescrew is "adjusted the plunger 4'3? advances or recedes, as the case maybe,andthereby*maintfiins control of fthe carriage with respect to angularmotion about the axis of the rod This adjustment serves to'sh-ift-theraceway laterally for the; purpose of regristration'with the insertiig'tool. The plunger 43wis-runder the stress of a compression spring 44,:the latter being maintained under compression by a screw-threaded sleeve45 screwed: into; a boss 46' in which the phinger slides, and" at thesame ti me affords a bearing" for the stein 47 otlhcp'plungcr.The-plunger 4:8 maintains frictional resistance td-movement of the car-vriage lengrthwiseof the rodfii notonly by its contactwith the wing '41but also by maintaii-iing pressure of the wing40 on the screw 42.This-serves-to control tl rlength wise "movements :01? the carriagenotwithstanding the fact that the latter isarrang'ed to travel aninclined path. fir-p actice the friction so appliedserves tomaintain'tho carriage in each of its extreme positions durinir theintervals of lost motionbetween it and the arm 22 bv which it is moved,toward and from"delivering" position. v 'llhedegree of friction may 'bevaried bv adjusting the sleeve 45' so as to compress the spring 4-3;more-o1: less. i

A horn. 48 formed on the carria-sie' is arranged toabut against the setscrew" 31 to determine the delivering position of the raceway. Thecarriage is further provided with two confronting lugs!) and 50 between'which the oper ating armQZ plays back alidff'orth with lost motion theextent of which maybe varied by anadjustablescrew 5.1 carried 'bvithc,luv; 50. As hereinbeforc stated the stationary screw 2; dete "minesthe[forward position of therarriage and ay be adjusted 'so asto registerthe delivery 1nd. oftlierac'eway withFthe inserting tool. then; is" thefactor that determines the initial positions of the movable elements ofthe machine. The lost motion ofthearm when the latter is moving from the'lug lg'to thes cire w' 51, enables the spindlel? to enter the leading'evelet-an the raceway before the retractory movement ofthe latterbegins. while the screw 51 provides for timing the beginning of suchretractory movement relatively to the movement of the inserting tool.When the elements start to return to their initial positions the racewaycarriage remains in its fully retracted position, under control of thefriction elements 42 and 43, during the first stages of downwardmovement of the inserting tool. This also is due to the lost motion ofthe arm 22 between the abutments 49 and 51, and enables the spindle 18to clear the new leading eyelet as the raceway returns to its initialposition. v

The member 36 of the carriage is provided with a flat elongated portion52 as a table or platform to reinforce the attached raceway. The latter,as shown, comprises a flat base plate 53 the upper end portion of whichis of a form and size such as to provide a bottom for the hopper throughwhich the fasteners are supplied to the raceway. The hopper includesalso an inverted cup-shaped member 54 which is preferably of ductilesheet metal stamped and affixed to the base plate by any suitable orpreferred means. The base plate also is preferably stamped from ductilesheet metal and is provided with ears at its longitudinal edges toafford supports for the guiding strips or plates 56. 56. These ears arebent upwardly as shown best by Fig. 6, and are provided with shoulders57 on which the strips 56 are seated. The reduced portions 58 of thecars are passedthrough holes in the strips 56 and are headed over orriveted. The base plate is further provided with notches 59 to receivethe shanks of clamping bolts 60. These bolts are arranged loosely inears 61 formed on the carriage portion 52 and are provided with wingnuts 62 by which their heads may be drawn downwardly to clamp theraceway to the carriage. -When the clamping members are relaxedtheraceway may be attached and detached by movement edgewise of thebase-plate, but it is not necessary to remove the nuts 62 from theirbolts. clamping bolts by which the raceway is detachably secured to itscarriage are separate and distinct from the operating mechanism and haveno effect in respect-to maintaining the component parts of the carriagein assembled relation. lonsequently the operation of taking off orputting on a raceway does not disturb the carriage mountings or theoperating mechanism.

The table portion 52 of the raceway carriage extends throughout almostthe entire length of the raceway and also under a substantial part ofthehoppe'r in order to reinforce the base-plate 53, especially at thejunction of the hopper and raceway. This feature of the carriage makesit feasible to It is to be observed that the two a set screw 68. As theraceway moves endwise the forked arm 66 plays back and forth on thestationary pin 67 and isthus oscillated to operate the brush 63, thefasteners in the hopper being thereby agitated and caused to escape inwell-known manner through an outlet port in registration with the slotformed .by the confronting edges of the guide strips 56.
